`Stratonovich-Weyl quantization on the Poincare half-plane'

Abstract: Motivated by the need to extend noncompact,
noncommutative manifolds beyond the flat case of the Moyal plane,
we rebuild explicitly the tracial quantization of the Poincaré
half-plane (or disk). Preserving the status of invariant
first-order differential operators under quantization is
a nontrivial task. We treat the half-plane as a coadjoint orbit
for the affine group, and build the quantizer accordingly.
The Wigner functions used in time-frequency signal analysis
emerge naturally from this construction.
